I started checking out zerotier.  This may obsolete VPNs for people telecommuting, and it provides real extension of access to remote devices over the internet.  Unfortunately it does not connect hidden networks that cannot reach the zerotier servers.  I read that they have a server download that will provide that for hidden networks. That may also decrease the fear of critical dependence on external (not within your own company) computing resources.  I have not figured out how to put a network printer or camera on a SDN yet.  We may need to share the printer port of  a computer on the SDN.  That remains unsolved to me.

I was able to set up a test software defined network in a few minutes.

Although I haven't tried it with openob, take a look at https://www.zerotier.com/

You can create your own Software Defined Network (SDN) which is private.  This will give you 'local IPs' to work with at each end with seemingly less overhead and issues than classic VPNs.

It's a brilliant system and worth getting your head around.  There are a number of Pi based instructions.  You shouldn't need to bridge or anything, just have the allocated IPs at each end and add routes if you need them going elsewhere in the network.

Richard,

Thanks very much for your crib sheet. It worked just fine for me and I am now up and running. Now I have my own notes to help me if I ever have to do this again!

 

Ted,

I see your point. This is a huge hole if it goes over the internet. I was debating running this STL over a VPN tunnel. You have swung me over and I will definitely do so after hearing about the redis security issues. Thanks very much for alerting me to this.

 

Thanks again guys!

Phil

Is this the correct version of g-streamer?

 

Below is a copy of a ‘crib-sheet’ that I put together for putting a Pi together for using OpenOB – this is using a Pi 3 not a 4 though and the ‘Audio Injector’ hat – but the OOB installation should be the same. This uses the April 2019 version of Raspbian, and the OpenOB version available in August 2019.

Install the prerequisites for OpenOB plus a couple other bits that are needed:

 

sudo apt install gstreamer1.0-plugins-base gstreamer1.0-plugins-good gir1.2-gstreamer-1.0 python-gst-1.0 python-redis python-gi python-setuptools gstreamer1.0-alsa python-pip screen

 

Install redis-server on the receiver:

 

sudo apt install redis-server

 

and configure:

 

sudo sed -i.bak 's/bind 127.*/bind 0.0.0.0/' /etc/redis/redis.conf && sudo service redis-server restart

 

Install OpenOB:

 

sudo pip install openob

 

---

 

For a previous build, I did at some point find a repository that had older versions of gstreamer in it and use it that way, but that was with the older openOB version.

 

Hope that's somewhat helpful at least!

 

Richard.

I am having difficulty getting prerequisites loaded on a raspberry pi 4. I’ve fixed this problem before but I cant seem to remember how I did it! Help please.

 

As an update for you all, I gave up on the Behringer UCA202s and its inherent mono problem have substituted a HifiBerry DAC+ ADC Pro for the input to the transmitter side, and a DAC+ Pro XLR for the output at the receiver side.

 

 

Thanks
